[PATCH v2] Docs/mm/damon/design: fix broken :ref: usage and a typo

[SJ Park <sj@kernel.org>]

From: "Zenghui Yu (Huawei)" <zenghui.yu@linux.dev>

The Statistics section refers readers to the DAMON sysfs interface
documentation for how to read the statistics, using a ':ref:' role.
However, the role name has a superfluous 's' appended (':ref:s' instead of
':ref:').  Moreover, its target label 'sysfs_stats' does not exist; the
correct label is 'sysfs_schemes_stats'.  Fix both.

Also fix a typo, 'frequenceis' -> 'frequencies', in the Adaptive Regions
Adjustment section.
